If the number of Old visitors buying Platinum tickets was equal to the number of Middle-aged visitors buying Platinum tickets, then which among the following could be the total number of Platinum tickets sold?
Explanation:
From points 1 and 2, the number of tickets bought by Young people = 80, the number of tickets bought by the middle aged people = 40 and the number of tickets bought by the old people = 20.
Using points 3 & 4, we get the following
Now all the questions can be answered.
We have, 20 - 2y = x + 2y - 20. Therefore, x + 4y = 40.
Therefore, x = 40 - 4y = 4(10 - y)
or 2x = 8(10 - y). Therefore, x is a multiple of 8. Out of the given options, 32 is a possible answer.
Hence, option (a).
